Fig benefits: the two constipation trials are real — but the pain itself did not improve

Key benefits

1. 01Early research

   Bowel measures improved; pain severity and the inflammation marker did not

   Two randomised trials that fed figs to people.

   2019, Explore — constipation-predominant IBS.

   • 150 patients with IBS-C, three groups (flixweed / fig / control), four months
   • Single-blind, not double
   • Assessed with the IBS severity score system and quality-of-life questionnaires

   Outcome	Result
   Frequency of pain	improved
   Distension	improved
   Stool frequency	improved
   Hard stool	improved
   Quality of life	improved
   Satisfaction with bowel habits	improved
   Severity of abdominal pain	no significant difference
   CRP (inflammation)	no significant difference

   The bottom two rows matter.

   First, the frequency of pain and its severity are different measures. Figs cut how often it hurt without changing how much it hurt. When stool softens, the number of painful episodes falls naturally. That is not the same as addressing the pain itself.

   Second, CRP did not move. Figs are widely introduced as an anti-inflammatory food. This trial does not support that. Four months of intake left the inflammation marker where it was.

   2025, Nutrition & Metabolism — constipation in pregnancy.

   • Ninety pregnant women with constipation, 30 per arm, double-blind
   • 15 ml of syrup daily, half an hour before bed, for 14 days, with two weeks of follow-up
   • Fig-walnut syrup / fig syrup / placebo

   Comparison	Result
   Fig-walnut vs placebo	significantly more bowel movements
   Fig alone vs placebo	significantly more bowel movements
   Fig-walnut vs fig alone	no significant difference
   Quality of life, fig-walnut vs placebo	mean difference −3.4 (p=0.008)
   Quality of life, fig alone vs placebo	mean difference −5.8 (p<0.001)
   Quality of life, between the two active arms	no significant difference (p=0.104)

   The walnut earned nothing. The expectation that a combination beats the single ingredient is not borne out by this data.

   The limits of these trials:

   • Both used a syrup or processed form, not whole fresh figs. The abstract does not say how many figs 15 ml of syrup represents
   • The 2019 trial was single-blind. When participants know what they are taking, questionnaire scores move easily — and every primary outcome here was a questionnaire
   • The 2025 trial ran 14 days with 30 people per arm
   • The authors close with "further studies are needed to reach a conclusive determination"
   • Both trials were conducted in Iran

   This site's conclusion:

   • For constipation there may be something here. Two trials point the same way
   • But do not read it as pain relief or as an anti-inflammatory effect. Pain severity and CRP did not move
   • The grade here is "early research"

2. 02Nutrition data

   16.3 g of sugar and 2.9 g of fibre per 100 g fresh — dried figs are another food

   Per 100 g of fresh figs:

   • 74 kcal, sugar 16.3 g, carbohydrate 19.2 g
   • Fibre 2.9 g
   • Potassium 232 mg, calcium 35 mg, magnesium 17 mg
   • Vitamin B6 0.113 mg, vitamin C 2.0 mg, manganese 0.128 mg
   • Protein 0.75 g, fat 0.3 g, sodium 1 mg

   Per medium fig (50 g):

   	100 g	One fig (50 g)	Three figs (150 g)
   Energy	74 kcal	37 kcal	111 kcal
   Sugar	16.3 g	8.2 g	24.5 g
   Fibre	2.9 g	1.5 g	4.4 g
   Potassium	232 mg	116 mg	348 mg

   2.9 g of fibre is high for a fruit, above an apple's 2.4 g. It is the first thing to reach for when explaining the trial results — not an exotic compound, just fibre.

   But sugar is 16.3 g. Three figs is 24.5 g, and the WHO recommends free sugars under 25 g a day on 2,000 kcal. Sugars held within whole fruit are not free sugars by that definition. Even so, if you manage blood glucose, know the number.

   Dried figs are not the same food. Drying concentrates the sugar and the energy. Do not apply the fresh-fig table above to them. A handful of dried figs is nothing like one fresh fig.

   The crunch of the seeds really is seeds. The edible part of a fig is an inverted cluster of flowers, and each small grain inside corresponds to a fruit.

   Choosing them. Figs do not ripen after picking. They have to ripen on the tree, which is why the season is short and they bruise easily. A ripe one wrinkles slightly at the skin and yields to a fingertip. A firm one will never sweeten.

   Refrigerate, two to three days. Store unwashed and rinse just before eating.

3. 03Not established

   "Fig enzymes aid digestion" — tenderising meat is a different claim

   This entry sorts through a common misunderstanding.

   Figs contain a protein-digesting enzyme called ficin. That much is true. It is concentrated in the milky sap and is genuinely used to tenderise meat, in the same family as pineapple's bromelain and papaya's papain.

   Then the story skips a step. "It contains a protein-digesting enzyme, therefore it aids digestion" tends to follow.

   Several things to check.

   First, this site has not found a clinical trial that fed figs and measured digestive function. The two trials above are about bowel movements, not about enzyme activity.

   Second, a swallowed enzyme has to survive the stomach, which runs at pH 1–2 and contains pepsin — an enzyme that digests proteins, including other enzymes. That an ingested protein-digesting enzyme stays active as far as the small intestine is a claim requiring its own evidence, not a free assumption.

   Third, the kitchen situation is not the same. Fig sap tenderising meat on a worktop means concentrated enzyme in direct contact for tens of minutes at room temperature. Eating a fig or two is not those conditions.

   So this site draws no conclusion in either direction here. That ficin exists is a fact; that it improves digestion when a person eats a fig is a separate claim that has not been confirmed.

   There is, however, something definite to say about ficin — the skin.

   The milky sap from fig stems and unripe fruit irritates skin. Handling a lot of figs can leave your hands stinging or reddened. Fig leaves and sap also contain furocoumarins, so skin carrying the sap can develop phototoxic dermatitis on exposure to sunlight. Wear gloves on a day of heavy fig handling, and wash the sap off.

   With a latex allergy, cross-reactivity to figs has been reported. Stop and seek care if your mouth itches or swells.
